microphone and built-in camera app not working

[nonresidentaliennico]

hey!

i installed ubuntu 24.10 on my machine (macbook pro m2 max). everything works perfectly except for the built-in camera app (the camera does work on browser but sometimes it's not recognized) and the microphone does not work at all. the system simply does not pick it up.

is there a workaround for this?

thanks a lot in advande!

Thx for the feedback! The gnome camera app seems to have a bug where it doesn't work properly with the camera on those machines yet. For the microphone if I remember correctly there was a known issue on the M2 Pro max too, afaik a fix in the form of a kernel update is WIP.

To make the camera work there are a couple of components affected:

you can update your table

	Arch
mesa	Fixed in Asahi ALARM mesa v25.2.5-2 (shipped already) see https://github.com/asahi-alarm/PKGBUILDs/tree/main/mesa see asahi-alarm/PKGBUILDs@0b7490e

[mkurz]

Also a couple of hours ago in Asahi ALARM we already shipped the patched kernel:

• https://github.com/asahi-alarm/PKGBUILDs/tree/main/linux-asahi
• asahi-alarm/PKGBUILDs@1dcf26f
• https://github.com/AsahiLinux/linux/releases/tag/asahi-6.17.7-1
• AsahiLinux/linux@b664d6e

So we just wait for the gtk 4.20.3 release and the pipewire 1.4.x patch release.

The fix for the microphone for M2 Max/Pro is now available since 6.17.12: AsahiLinux/linux@2eb134c

Fixed for Noble/Questing: linux-asahi-arm (6.17.0-1001.1): https://launchpad.net/~vpeixoto/+archive/ubuntu/asahi

[mkurz]

Arch Linux shipped pipewire 1.4.10 a couple of hours ago with the fix: https://archlinux.org/packages/extra/x86_64/pipewire/
(edit: I can confirm this update also landed in Arch Linux ARM)

[reviczky]

Fixed PipeWire version 1.5.85 (https://gitlab.freedesktop.org/pipewire/pipewire/-/releases/1.5.85) is now also packaged for Debian: https://tracker.debian.org/news/1708643/accepted-pipewire-1585-1-source-into-experimental/

[tobhe]

Not sure if it would make sense backporting 1.5.85 from Debian to Ubuntu/Questing, what do you think?

In the meantime I uploaded a 1.4.7 build with the two fixes backported at https://launchpad.net/~ubuntu-asahi/+archive/ubuntu/ubuntu-asahi-next?field.series_filter=questing

[reviczky]

1.4.7 + fixes should be fine for Questing. I will be also testing on Resolute with 1.5.85 or later when it is synced from Debian.
Would be probably worth having the gstreamer1.0-gtk4 fix backported as well. 1.14.4 is now being synced in Resolute: https://bugs.launchpad.net/ubuntu/+source/rust-gst-plugin-gtk4/+bug/2137027

[tobhe]

Synced from Debian to ubuntu-asahi-next, let's see if that works.
